Hmm. What the hell am I supposed to do about
(II) NOUVEAU(0): [drm] nouveau interface version: 0.0.16
(EE) NOUVEAU(0): [drm] wrong version, expecting 0.0.15
(EE) NOUVEAU(0): 879:
What happened to the whole backwards compatibility thing? I wasn't even
warned that this breaks existing user space. That makes it impossible to
_test_ new kernels. Upgrading X and the kernel in lock-step is not a valid
model, lots of people are just using some random distribution (F12 in my
case), and you just broke it.
I see the commit that does this was very aware of it:

drm/nouveau: new gem pushbuf interface, bump to 0.0.16
This commit breaks the userspace interface, and requires a new libdrm for
nouveau to operate again.
The multiple GEM_PUSHBUF ioctls that were present in 0.0.15 for
compatibility purposes are now gone, and replaced with the new ioctl which
allows for multiple push buffers to be submitted (necessary for hw index
buffers in the nv50 3d driver) and relocations to be applied on any buffer.
A number of other ioctls (CARD_INIT, GEM_PIN, GEM_UNPIN) that were needed
for userspace modesetting have also been removed.

but why the hell wasn't I made aware of it before-hand? Quite frankly, I
probably wouldn't have pulled it.
We can't just go around breaking peoples setups. This driver is, like it
or not, used by Fedora-12 (and probably other distros). It may say
"staging", but that doesn't change the fact that it's in production use by
huge distributions. Flag days aren't acceptable.
